How do I find the factor combinations of the number 496,903?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 496,903, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 496,903
-1 -496,903

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 496,903.

Example:
1 x 496,903 = 496,903
and
-1 x -496,903 = 496,903
Notice both answers equal 496,903

With that explanation out of the way, let's continue. Next, we take the number 496,903 and divide it by 2:

496,903 ÷ 2 = 248,451.5

If the quotient is a whole number, then 2 and 248,451.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 496,903
-1 -496,903

Now, we try dividing 496,903 by 3:

496,903 ÷ 3 = 165,634.3333

If the quotient is a whole number, then 3 and 165,634.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 496,903
-1 -496,903

Let's try dividing by 4:

496,903 ÷ 4 = 124,225.75

If the quotient is a whole number, then 4 and 124,225.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 496,903
-1 496,903
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

1111992272,1892,49745,173496,903
-1-11-199-227-2,189-2,497-45,173-496,903
